ABSTRACT:
Provided are a pointing device allowing accurate depressing operation on a key top and involving no erroneous input or erroneous operation, and a key sheet for the pointing device. On the back surface of a base sheet (14) of a key sheet (15) for a pointing device, an accommodating portion (17) for a magnet (13), for accommodating portion greatly protrudes toward a board (P) beyond a pusher (14b) is provided. When the key top (12) is depressed, the accommodating portion (17) and the magnet (13) come into contact with the board (P), and causes the depressed key top (12) to tilt using the point of contact as a fulcrum, thereby pressing the pusher (14b) against a contact switch (Pi, Po). Thus, it is possible to reduce the thickness and weight of the pointing device (10) and the key sheet (15) for the pointing device. Further, a reduction is achieved in terms of the possibility of erroneous input and erroneous operation, making it possible to reliably effect confirmation input.
